Lesson 6: Brownie Fund Me - CompilerError: File outside of allowed directories

[ace-brown]

Hi guys.
At around hours 5:10 I encountered this error.
CompilerError: solc returned the following errors:

really odd. Everything looks right. This error means it can't find that folder.

what version of python are you using?

[ace-brown]

Yeah that's really odd. I've got installed python version 2.7, 3.9 and 3.10 on my 64 win10. But on the system environment, I set all my paths to python 3.9.

[cromewar]

It's not brownie_config.yaml is brownie-config.yaml with - so that's why your brownie can't find the configuration, give it a try ;)
Best regards.

[ace-brown]

That's it. It was the underscore keeping me form going on for 2 days. lol. BTW, thank you so much man.

[cromewar]

You are welcome, I'm glad it helped.

[pgraciae]

Had the same problem here! Thanks!

[s1n7]

I have the same issue. I spelled the "brownie-config.yaml" folder correctly. However, the error still occurs.
My files have the same content as the ones posted here. The only difference is that I use a virtual environment, so my folder structure is a little bit different:

The "dev" folder contains the contracts, scripts etc. and the "virtualenv" folder contains everything that belongs to the virtual environment.
Can someone help?

[s1n7]

additional information: my solidity version seems to be the problem:

[cromewar]

just right, change the global compiler version - remote and set it the version you need. If you have compiler error also attach them here please.

[s1n7]

you mean right clicking on that and then select "Solidity: Change global compiler version (remote)"? And which version should I select?
I'm sorry, I do not fully understand how to use the versions yet...

[cromewar]

There are some thing to take in consideration here, the extension provided by Juan Blanco is by far the best for Solidity development, however it has its faults, for example let's suppose you are going to work with a project using solidity version 0.8.0, so you should change the compiler version to it and it should work, but, what if you import another file which uses an anterior version? for example a Mock, and the mock has something like this:

pragma solidity ^0.6.0;

Event tough the compiler will work just fine, because you have the ^ symbol (meaning that you could use that version of the compiler or any another one higher) the VScode Extension is going to complain about the version you are using are not the same as in the file.

My recommendation, just use the compiler version according to your main contract file, ^0.6.6 or 0.8.0 in most cases (that I've seen) and for test contracts don't pay attention to vscode complaining to them (as long as your main compiler is higher to the required version).

Remember changing between version is as simple as right click and select the option.

[Xingfu-Yi]

Perhaps it's a grammar mistake in brownie-config.yaml , i wrongly type the word commpiler and that's the case

[cromewar]

Nice hint @steven2077

[PP-AR-T]

I got the same problem, and can't find the reason no one of the listed above

[tredw]

Hi - I have the same issue and the solutions above have not worked.

.

Below is the brownie-config.yaml file:

I also added this to settings.json file
"solidity.remappings": [
"@chainlink/=/Users/Tim/.brownie/packages/smartcontractkit/chainlink-brownie-contracts@1.1.1",
"@openzeppelin/=/Users/Tim/.brownie/packages/OpenZeppelin/openzeppelin-contracts@4.4.0"

[cromewar]

@tredw it seems your brownie-config.yaml is inside your test folder, is it?
if that's true, it must be on the project root directory.

[tredw]

Thanks! You're right much appreciated. Lesson I've learnt from this is sometimes when stuck just need to re-watch video from the beginning of lesson you're on and go through the coding process again to hopefully catch what you missed the first time.

[Yadu-blockchain]

Thank you so much man! I was working with this problem for a very long time. Finally.

[realglass]

Hi! I am a complete noob at this but learning quickly. It seems I got suck here and can't figure out what is the problem. Any help pls??

here is my brownie-config.yaml

[cromewar]

Hello @andrewvella1991 I don't see the mockContract on your contracts folder, you must create a folder called tests and put there the MockContract.

[tolivern]

Maybe it is because you wrote "dependecies" instead of "dependencies"...? (I am noob as well)

[cromewar]

yes you are right @tolivern 100% missed it

[Abdel364]

Hello Please can some help me with this issue, i got the some issue of you guys but i don't know where is the problem

This is the contract:

[rohit9888]

it is remappings not remapping. add 's'

[harshpreetwmk]

thanks brother love you

[ajimoti]

I had the same error, apparently, I didn't leave a space between the - and '@chainlink=smartcontractkit/chainlink-brownie-contracts@1.1.1' in my remappings.

Solved it by adding the space
